The Aiphone TAR-3 Call Extension Relay is used to activate an external doorbell or signaling device when a door station calls in. It can be used for call extension on the IE, MY (for door call), IE-8MD, YKX, TB-M, and AT systems.
When used with the IE and MY systems, this relay allows the integration of a standard doorbell, which will ring when a call is placed from the door station. For the IE-8MD, YKX, TB-M, and AT-406 systems with the relay at the remote station, the external device will be activated as long as the handset is ringing.
